Handed in to me by a householder who had it growing in garden. Probably birdsown.
No interactions present.
Any chance of a photo of the older leaves further down the stem and of the whole plant?

Hope these enlighten you. It's really puzzling me!
The berries do look characteristic of Solanum don't they? An enormous genus, of course!

basal leaf and general plant form pics added.
Confirmation from Solanum expert at the Natural History Museum:
"The plant in question is indeed Solanum laciniatum Aiton â€“ it has become established all over London in recent years; it was originally brought to the UK by Joseph Banks from New Zealand. It is called kangaroo apple.
Hope this helps!
